Product Introduction:
|
HLS-1701ELB/HLS-1701EG Black Cationic Epoxy Electrocoat for auto is a new generation electrophoretic coating researched and developed by HLS Paint (Shanghai) Co., Ltd.
|
|
It represents modern technology of cathodic electrophoretic coating that is environment-friendly with high property and low cost. Such coating does not contain heavy metal like lead, tin, cadmium and mercury etc. It is a two-component, water-dispersed resin,meanwhile, it took in features of previous products, and can adapt galvanized steel sheet perfectly, almost can be applied to foundation coating of all metal, such as: cold and hot rolled steel sheet, galvanized steel sheet, aluminum products, zinc-aluminum alloy sheet and stainless steel sheet etc.
|
This product features shown below:
①,Strong anti-corrosion properties, good salt spray resistance workpiece edge
②,The bath has strong anti-shrinkage and anti-pollution ability
③,Ideal for high demand for salt spray industry, such as pipe trench, auto chassis parts, castings
The main component Matrix resin :
|
Pigment: carbon black, kaolin, antirust pigment
|
Solvent: alcohol ether |
|
Additives: surface active agent, prevent shrinkage cavity agent
|
|
Matrix resin: polyurethane modified epoxy resin
